The Imperial State Crown, one of the infamous Crown Jewels that symbolises sovereignty, weights 1.28kg.

The documentary focuses on her coronation back in 1953, in which she was passed down the jewels.

Taking over the throne from her late father, George VI, the Queen revealed: “Fortunately, my father and I have about the same sort of shaped head. But once you put it on, it stays. I mean, it just remains on.”
